Filtering timestamp columns

[mkaunisaho]

Previously this kind of filter statement would've worked:

Now it throws the following error:
'<' not supported between instances of 'Timestamp' and 'str'

I can't figure out how to edit the statement. If I use datetime_col < datetime.datetime(2023,12,5,10,30) I get the error name 'datetime' is not defined

I am using pandasgui 0.2.14
